The title compound, [Ru(C18H33P)2(CO)3]·C7H8, shows a distorted trigonal-bipyramdial coordination around the central boxes Ru atom, with the two phosphine ligands occupying the axial positions.Two toluene molecules per asymmetric unit with site-occupation factors of 0.5 are observed.

One of them forces two of the CO ligands to enclose a wider C—Ru—C bond angle [127.5 (3)°] than in the solvent-free crystal structure of Tote Bag [Ru(PCy3)2(CO)3] (Cy is cyclohexyl).
